REFRIGERATOR COMPANY, OF ST. PAUL, MINNESOTA, A CORPORATION OF MINNESOTA MECHANICAL REFRIGERATION Application filed November 5,1926. Serial No. 146,385.

My invention relates to mechanical refrigeration, and particularly to domestic mechanical refrigerating units, and the particular object of my invention is to provide a new and improved unit of this type. In the drawings accompanyin this specification. and forming a part of this application I have shown, for purposes of illustration, three forms which my invention may assume. In

' these drawings Figure 1 is a front elevation of a refrigerator cabinet shown with the door open, and

with certain parts broken away, and showing the first embodiment of my invention illustrated herein,

Figure 2 is a section on the line 2-2 of Figure 1,

I Figure 3 is a fragmentary View similar to Figure 1 showing thesecond embodiment of my invention illustrated herein,

Figure 4 is a view similar to Figure 1 showing the third embodiment of my invention illustrated herein, while Figure fi is a section on the line 5-5 of Figure 4. I

In Figures 1 and 2 I have shown my invention as applied to a refrigerator cabinet 11 provided with a shield 12 segregating the space within the cabinet 11 into a refrigerating compartment 13 and a refrigerated compartment 14, and containing within the refrigerating compartment '13 mechanical refrigeratingapparatus 15 herein shown as a brine tank 16 provided with a refrigerant expansion coil not shown extending between a refrigerant expansion valve 17 connected to a suitable supply of condensed refrigerant, and refrigerant end turns 18 connected to a suitable refrigerant compressing mechanism and supporting a thermostat 19 controlling the action of this refrigerant compressing mechanism, and provided also with recesses 20 for the reception of pans 21 for the formation of artificial ice under the action of the mechanical refrigerating appa- "ratus.

Also mounted within the refrigerating compartment 13 beneath the brine tank 16 is a pan 22 suitable for the storage of artificial ice formed in the ice pans 20 under the action of the mechanical refrigeratingapparatus, suitable also for the collection and reception of condensation dripping from the mechanical refrigerating apparatus, and supported for removal from the refrigerating compartment 13, and from the refrigerator cabinet 11, by means of an extension 23 of the shield 12 carried across beneath the refrigerating compartment 13 to the adjacent out-side wall of the refrigerator cabinet 11, provided there with upturned feet 24 by means of which it may there be secured to the outside wall of the refrigerator cabinet 11, and provided intermediate its front and back edges with apertures 25 for the assage of the air circulating through the re rigerator cabinet 11 formed by stamping out from I the extension 23 flan es 26 upturned to provide side members e ective to guide the pan 22 as it is inserted and removed from its position within the refrigerating chamber 13 beneath the refrigerating apparatus 15.

In the embodiment of my invention shown in Figure 3 1' have shown the refrigerator cabinet 11, and a shield 27 separating 0d the refrigerating compartment 28, and the refrigerating apparatus 15 disposed within this refrigerating compartment 28, and a pan 29 for storing artificial ice produced under the action of the refrigerating apparatus 15, and for receiving and retaining the condensation dripping from the refrigerating apparatus 15, and I have shown this pan 29 as provided at this upper edge with a projecting rim 30, and as supported by the engagement of this rim on one side with I a rail 31 fixed to the outer wall of the re-' tical partition 34 anda horizontal partition 35 segregating a refrigerating compartment 36 containing the refrigerating apparatus 15, and I have shown within this refrigerating compartment 36 a pan 37 again suitable to receive the artificial ice formed by the mechanical refrigerating apparatus 15, and

lea.

again suitable to receive and contain the condensation dripping from the mechanical refrigerating apparatus 15, and supported by means of apair of rails 38 secured upon the 5 upper face of the horizontal partition 85.

From the above description it will be obvious to'those skilled in the art that I have provided a domestic mechanical refrigeration unit accomplishing at least the principal object of my invention. I

At the same time it will also be obvious to those skilled in the art that the particular embodiments of my invention herein shown and described may be variously changed and modified without departin of my invention or sacri cing the advantages thereof, and it will therefore be understood that the disclosure herein is illustrative only, and that my invention is not limited thereto.

said chamber into communicating compartments, one of said compartments being adapted to receive a cooling unit, and means forming a part of said shield within said last mentioned compartment adapted to support a removablepan beneath the cooling unit.

2. In a mechanically refrigerated cabinet, a chamber, a shield dividing said chamber into communicating compartments, one of said compartments eing adapted to contain a cooling unit and a removable pan in spaced relation, said shield supporting said an, said chamben having an opening aflt'or ing access to substantially the entire last mentioned compartment, and pan supporting means carried by said shield. I

3. In a mechanically refri erated cabinet, a chamber, and a shield divi ing said chamber into communicating compartments, a cooling unit in one of said compartments, a removable drain pan disposed beneath said cooling unit, portions of said shield being bent to form flange means adapted to guide and support said pan. p

4. In a mechanically refrigerated cabinet,

a chamber, and a shield member dividing said chamber into communicating compartments,

- a cooling unit disposed in one of said compartments, a removable drain beneath said unit, said shield avingopenings formed theret-hrough by struck outportions, said portions being adapted to guide said removable drain pan.

5. In a mechanically refrigerated cabinet, a chamber, a shield member dividing said chamber into communicating compartments, one of said compartments being adapted to contain a cooling unit, and a pan supporting means associated with the wall of said last mentioned compartment formin a part of said shield beneath the cooling unit space.

" 6. In a mechanically refrigerated cabinet,

from the spirit 1pan disposed neath the cooling unit, and pan supporting means forming a part of said shield and formed integral therewith.

In testimony whereof I hereunto afiix my signature.

CHARLES C. SPREEN.
